Gday guys just thought id write in and say its time for a new water pump, found it leaking pretty hard during the week. Has anyone elses gone at around 120k's ? Anyway my question is when i put a little coolant in to it up and let it run for like 30 secs i opened the radiator cap and there was foamy type bubbles at the top of the radiator does anyone know why that happened? Engine being to hot maybe? Also im getting it changed on Monday is there anything esle my mechanic should look at/change due to the water pump dying. Any feedback is appreciated thanks

Well if he is doing the water pump now is a good time for a timing belt change, tensioners, front seals, flush/upgrade/renew radiator. Also, not sure if its the same on an R33 but on my RB20 there is a welch plug behind the water pump which had corred a lot on mine so I guess change that as well.

If your mechanic didnt suggest a new timing kit while doing the water pump I would be very suprised.

u may as well do everything while u have all ur belts off... if ther is foaming bubbles u might also have a air lock.. if its really bad and cant fix it.. u might have to rip ur head off and recon than. careful not to blow ur head gasket in this weather. or u will rip ur head off.. then u can get ur tbelt cam seals front seals tensioners all done.

how do you know what the water pump has carked it? leaks all the coolent, and temp goes skyhigh?

Well with mine there is a small hole under the water pump, (built in safety item) when the seal goes on the water pump water will leak out of the hole under pressure. I had been using a little bit of water, We did a rad comp test, changed hose clamps and still could not find the leak, Then one morning when I started my car I noticed a bit of coolant coming from under the car, and when temp built up it would stop leaking, I then decided to check the water pump. Anyway that’s on my RB26.

Mine's just going at 115,000km..

bubble, bubble.. Hopefully yours hasn't cracked the head or blown the gasket..

I've always stopped when its got to 3/4 on the temp gauge.

most people change it @ 100k... as thats what the 100k service involes.

Going another 20k is asking for trouble!

;)

Wow that was a big reply thanks guys, cars now back on the road. When i bought the car it just had the timing belt done but i dont know what else. My mechanic did a pressure test and everything was ok but i dont know if the tensioners were changed by the last owner. What sort of damage would happen if they fail or what are the signs of them going? didnt have enough money to get them changed this time :blink:

      High temp brake fluid?

      By robbo_rb180 · Posted

      I use the penrite 600f in my cars and have had no issues even at Townsville v8s when I drove that but I bled fluid end of day for just in case. Good value and a about 38-40 on sale. Use castrol srf on the supercars and no need to Bleed brakes over a race weekend. Do the 1000km with no issues. Over 120 a bottle I seen at repco. A quality brake pad is always a good starting point the ebc stuff I've seen let go after 2 sessions with heavier cars. I'd be going to a decent track pad and maybe those porsche air guides on the control arm to help with some air over the rotor. Helps on 86/brz with stock callipers.

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣
